Title: Improvements in enteric coatings for medicaments
IPC: A61K9/48
Filed: 1939-03-11
Abstract: 526,276. Coatings for medicaments. KODAK, Ltd. March 11, 1939, No. 7907. Convention date, March 11, 1938. [Class 81 (i)] [Also in Group IV] Medicaments are covered with an enteric coating of a cellulose derivative containing free carboxyl groups. Such substances are prepared by reacting cellulose or a cellulose derivative containing free and available hydroxyl groups with a polycarboxylic acylating agent either in the presence of a tertiary organic base or in a suitable solvent. Examples are given in which cellulose, cellulose acetate and ethyl cellulose are reacted with phthalic anhydride and succinic anhydride. In one example, cyclohexane is used as a solvent. Other cellulose derivatives which may be used for the reaction are the propionate, butyrate, acetatepropionate, acetate-butyrate and the butyl and benzyl ethers ; diglycollic and maleic anhydrides are mentioned as other acylating agents. Increase in the amount of inert ester or ether in the product gives a decreased solubility in water, acid and alkali, while increase in the free carboxyl content causes increase in the solubility in alkali. The preferred carboxyl content is 5-25 per cent. and particularly the range 9-15 per cent. The substance to be coated may be dipped direct in a solution of the product in a suitable solvent or may be first covered with gelatine. The solvents used in the examples are dioxan, a mixture of ethylene dichloride and methyl alcohol and a mixture of ethyl lactate, water and ethyl alcohol. Triacetin, tripropionin, ethyl acid phthalate, butyl acid phthalate and ethyl acid adipate may be incorporated with the cellulose derivative to act as plasticizers and also fats and waxes may be added.

Title: Improvements relating to the production of long lengths of metal jacketed electric cables
IPC: H02G15/18
Filed: 1936-03-19
Abstract: 452,703. Cables. SIEMENS-SCHUCKERTWERKE AKT.-GES., Siemensstadt, Berlin. March 19, 1936, No. 8255. Convention date, March 30,1935. [Class 36] In the manufacture of long lengths of metal jacketed electric cables having an insulation of material which is of greater sensitiveness to heat than paper, the insulation of the core conductors prior to stranding them into the cable, or the insulation of the cable core, in sections of the cable located at definite distances apart corresponding to the distances between the stopping points in the extrusion of the metal jacket, consists of insulation material such as paper, asbestos and the like, which is comparatively insensitive to heat, the jacketting extrusion press being stopped and recharged within these sections during the extrusion of the metal jacket on to the cable. The Figure shows a cable with quad conductors 1 ... 4 provided, over the major portion of their length, with insulation of polystyrol which, at positions 5, merges into paper insulation and then, at the positions 6, again into polystyrol insulation. The transition from one form of insulation to another is effected gradually in steps in respect of the different conductors to prevent as far as possible any thickening of the cable core. A polystyrol band winding 7 over the quad is terminated as shown and replaced in the special section by a paper band insulation (not shown). The paper band winding between the points 5, 6 may be marked, for example, by a dark colouring, so that the extrusion press in extruding the lead jacket 9 can be stopped at this point for recharging. The " bamboo rings " formed on the lead jacket at the stopping positions provide marks which indicate the stopping positions when a second lead jacket is being extruded thereon.

Filed: 1974-02-26
Abstract: 1455482 Crash bags for passenger vehicles NIPPON SOKEN Inc 26 Feb 1974 [27 Feb 1973] 8599/74 Heading B7B A crash bag comprises a bladder 4 which is distended in the event of a collision by the inflation of chambers 6 formed adjacent the bladder wall. During inflation, air is sucked from the passenger spaces into the body 8 of the bladder through apertures 7. The arrangement allows the bladder to be distended using less gas than would be necessary to inflate the whole bladder, and, by sucking air from the passenger space, ensures that there is no harmful pressure rise in that space. In the illustrated embodiment, the chambers 6 are formed by the bladder wall and by a synthetic fibre insert 5 which is sewn to the bladder. To distend the bladder, communication is opened between a compressed gas bottle and a diffuser 2 so that gas is injected into the open ends of the chambers 6 from diffuser apertures 3. When a vehicle occupant is thrown against the distended bladder, gas is expelled directly from the body of the bladder through the apertures 7, and gas is also expelled from the chambers 6 through the apertures 7 after first passing round the edges of the insert 5. In a modification, Figs. 6 and 7 (not shown), the inflation chambers are formed by tubes in a bladder insert, the tubes being connected directly to the diffuser apertures. In this case, when an occupant is thrown against the bladder, gas is expelled only from the body of the bladder.

Title: Process of preparing monohydric alcohols
IPC: C07C29/09
Filed: 1937-03-24
Abstract: Aliphatic monohydric alcohols are made by hydrogenating a nitrile or mixture of nitriles having six or more carbon atoms to produce the amine while in acid solution, using a platinum catalyst, and then treating with a nitrite.  The alcohols produced may have 6-19 carbon atoms or more, and may be saturated or unsaturated.  In an example, lauronitrile is hydrogenated in hydrochloric, sulphuric, glacial acetic or acetic acid solution with a platinum catalyst, ethyl alcohol being added as a solvent. To the reaction product is added more ethyl alcohol and sodium nitrite.  After the reaction an alcoholic layer is separated and the product is washed with acidified aqueous alcohol and then with hot water.  When the initial material is a mixture of nitriles the mixture of alcohols produced may be separated by fractional distillation under reduced pressure. Specifications 467,043, 467,044, and 477,463 are referred to.
